Do you happen to know whether we have reason to suspect that the aldehyde and refrigerator approach will be measurably less effective for future use of the stored brains, vs conventional cryopreservation?
Both aldehyde fixation and liquid-nitrogen cryopreservation are techniques easy to perform, and routinely employed in ~every biology lab for cell cultures. Reversing the latter is trivial and also routine; reversing the former is not possible with current tech.
How relevant you consider this is up to you. My guess is that people intuit that with improved technology, the relative difficulty of reversing these on the macro scale would be the same.
If the aldehyde preservation method is as good as traditional cryopreservation, then this looks like a pretty glaring market inefficiency—someone should be able to swoop in and undercut the established cryo companies.
I just don’t know enough about the object level arguments to say much with confidence, but I’m a bit skeptical such a gap in the market exists.

I don’t know. The brain preservation prize to preserve the connective of a large mammal was won with aldehyde-stabilization though
